You can try to pour some white lepage’s/bond-fast type glue on top of the area, wait until it dries, then when you peel it off the splinter usually follows.
If this fails, soak splintered area in epsom salts.
If these fail, resort to needle and tweezers; cleanse afterwards to avoid infection:)

I’m bad with things like needles and splinters. When I was in elementary school (6th grd-ish) they had to call my mom to come and get a splinter out for me. I disperse violence indiscriminately when it comes to pain, Dr’s and Nurses get no passes. And I still cried like a baby.

A week ago my boyfriend was playing basketball at a school gym. He slid down the bench to reach his water and was greeted with a sharp pain on his butt. Reached down and grabbed 2 of the 3 INCHES of wood stuck in his flesh. He played the rest of the game with the remaining wood and called me for medical assistance on his way home. I got the rubbing alcohol out right away and waited by the door with a pair of tweezers and a needle in hand. I took one look at his bare butt and told him to go to the hospital. He willed me along, desperate for some relief and eventually
after much yanking and tugging at the tiny tip of the splinter I ripped out a full inch of wood that was thicker than a toothpick. I can’t say it was awesome but it makes for a good story…awesome.

Cusin had fallen in the bush and a stake was pointing up and he landed his ankle on it :( but i didnt realise this until there was blood and tears everywhere, so i carried him home ( feeling awesome about that ) and he had splinters in his ankle really badly and we thought we got it all but a week later he had an operation ,as a scan had showed a tiny splinter in his blood stream halfway up his leg, so they had to cut it out and now the result is a ‘dint’ looking scar on his leg :/ not as great as using the good old tweezers and needle :)
